[stella] programming on PDAs

Has anyone had any success programming for the 2600 from a PDA such as a
PocketPC? Anyone port DASM? There is a 2600 emulator for PocketPC but I
don't know how well it runs on today's ~200mhz models. If they can reach
100% throughput then these might make good portable development
environments, or just game players. Intel's XScale systems will be coming
out soon with ~400mhz CPUs so I'm sure it's just a matter of time. But
with current systems like the Audiovox Maestro on sale for less than $300,
it's tempting to pick one up, as that's about what it would cost to build
something like a portable VCS anyway-- but with all the added flexibility
of a small computer on top. There is also the Linux-based Sharp
Zaurus. Stella could probably be ported to it pretty easily.

Unlike the the lower oddball-resolution Gameboy Advance, PocketPC devices
have a 240x320 res screen which is ideal for emulating classic raster
videogames without the need for uneven pixel scaling. Of course, for
systems with a horizontal display, you'd need to rotate the PDA 90'.
